This is a method of calculating the vehicle speed by storing the number of pulses per rotation in the memory in the vehicle speed signal conversion controller 7. Still another one is, as shown in FIG. 4, actuating the vehicle speed signal adjusting switch 8 in a state in which the tires of the vehicle are rotated at a specified speed, and The output signal frequency is stored at a designated speed, and a vehicle speed proportional to the frequency is obtained with the value stored as a reference.

The step of detecting whether or not there is, and after detecting the pulse signal input from the vehicle speed sensor when the switch for vehicle speed signal adjustment is in the “ON” state as a result of the detection, set the reference input pulse number per unit speed. After that, the step of detecting whether or not the vehicle speed signal adjusting switch is in the setting state of the reference input pulse number as in the state of being “OFF”, and the detection result, if the reference input pulse number is not in the setting state, If the state is further returned to the step of detecting the vehicle speed signal adjusting switch state, and the detection result, the setting state of the reference input pulse number,
After measuring the pulse signal input from the vehicle speed sensor, the vehicle speed is calculated by comparing the measured pulse number with the reference input pulse number, and then the number of pulses (frequency) output per unit time at the calculated vehicle speed And outputting the pulse signal to the electronic speedometer or the electronic operation recorder, and then returning to the process of detecting the switch state for adjusting the vehicle speed signal, the method for converting a vehicle speed signal.
